To LU whom it may concern.-

Beit known that i, MARY-E. GILMORE, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode lsland,a1n the administratrix of the est-ate of ROBERT J. GILMORE, deceased, late a citizen of the United States, and a resident of said Providence, who invented certain new and useful Improvements in Tater-Motor Ap para-tus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

.ln a patent of the United States,No.557,2G3, issued. to Robert J. Gilmore and C. A. Dunlap on the 81st day of Marcin 1896, is shown and described an automatic fountain possessing certain novelfeatures. In the fountain referred to the mechanism employed is arranged to operate intermittingly, such changing action being utilized tol produce different designs or displays, the changing action being effected, primarily, (as drawm) by means of a tripping device capable of being released through the medium of a slowly flowing stream of Water.

The Water-motor forming the subject of the present invention iswell adapted to be employed in lieu of the intermittent tripping de vice just referred to, and, in fact, it may be successfully used for other purposes Where intermittent power is required.

The improved water-motor consists, essentially, of an oscillating device comprising a double bucket of novel construction and capable of being made operative by water iioW- ing into it from any convenient source, as a faucet, brook, the. By means of the iinprovement Water-motors of this type are rendered more positive in action. lt is simple in construction. A greater Ypercentage of useful Work is developed. The cost of production is materially reduced. Itis self-contained and automatic, and its continuous performance is limited only by a cessation of 5o `the Watersupply. v

In the accompanying vsheet of drawings,

Serial No. 626,901. (No model.)

Figure 1 is a side elevation, in partial sec tion, showing the improved Water-motor connected with valve-operatin g mechanism forming, say, part of an automatic fountain. Fig. 5 5 2 is a transverse section taken on line a' a; of Fig. l. Fig. 3 is asimilar sectional view showing the other extreme position of the motor. Fig. 4 is a transverse sectional View, in enlarged scale, taken on line .a e of Fig. l; and Fig. 5 is a similar section corresponding with the position shown in Fig. 3.

a, referringto the drawings, designates the bucket portion of the improved Water-motor. It consists, essentially, of two principal parts or suitably-shaped chambers h h' and c. As drawn, the chambers are independent of each other and are preferably arranged as shown in Fig. a, the upper portion extending laterally beyond the lower chamber portion c and forming an offset. Atthe intersection of the said chamber members is fixed an axle or shaft d, the ends of the latter projecting so as to form journals, which in turn are mounted in the side frames or standards m.

The normal relation of the chambers to each other when mounted is such that they are nearly counterpoised. The upper chamber member h is open on top, so as to freely receive Water from an open pipe p, the latter conducting Water from any suitable source of supply. The other part b of said chamber is separated therefrom by a partition 1l, the same extending nearly to the bottom of the bucket or chamber, as clearly shown in Fig. 1i.' To the left of and contiguous to the chamber portion h' is formed an auxiliary chamber h2, communication between them being effected through an opening o, located in the wall separating the chambers, said opening being Xed at any desired point. Thus it will be apparent that When the Water-level rises to the opening o the former balance of the parts Will be automatically changed by reason of the Water flowing through said opening into the chamber b2. The Weight of the Water passing into the latter chamber acts to change the equilibrium, owing to the greater leverage thus produced, thereby causing the apparatus to instantly swing on its axis, say, ninety degrees, or to the position shown in Fig. 5. It will be noted that the partition prevents the ICG water from overflowing when the bucket suddenly changes its position. The outer ends of the chambers b b2 are provided with suitable discharge-openings 0 o2, respectively, through which the water escapes, the degree of such outflow being controlled by the size of the openings or exit-passages.

It is obvious that when the apparatus changes its position, as just described, the lower chamber c will thereby be elevated into position directly under the pipe p to receive water in turn. As soon as the rising waterlevel exceeds the weight of the dischargingchambers the bucket will swing on its axis automatically back to its normal position, such movement being practically instantaneous and positive, owing to the outer extension c2 communicating with chamber c, into which the water quickly flows whenever a corresponding change in the equilibrium of the parts takes place. The chamber portion c2 is provided with a discharge-outlet c', through which the water passes while the other chamber Z2 IJ is being refilled. (See Fig. 4.)

In order to utilize the force produced by the oscillatory movements of the bucket members a, the axle d may be provided with a bevel-gear /,arranged in front of one of the standards fm, the latter carrying a bea-ring in which a short horizontal shaft c is mounted. To the inner end of said shaft is secured a small bevel-gear g', intergearing with the fellow gear g. The opposite end of shaft e has -a crank c fixed thereon, which in turn is jointed to a link l, as shown in Fig. 2. As drawn, the diameters of said gears are such that each oscillation of the bucket will rotate the shaft e one-half a revolution.

Fig. 1 shows how the movements of the bucket may be converted into useful work. In said figure the mechanism represents certain portions of an automatic fountain and contained within a casings. The mechanism is arranged to intermittingly open one or more valves o, connecting the inlet and outlet pipes u u', respectively. The valve is adapted to be actuated by an arm or lever n', its free end being in engagement with a suitable cam-wheel o2, secured to the shaft f, revolving in the fixed bracket or base t. To the shaft f is also secured a ratchet-wheel w, actuated by a pawl h', jointed to the swinging varm h, the latter in turn being jointed to the link Z, before described. Thus it will be apparent that the action of the bucket in oscillating to its limit in one direction will cause the shaft f and its attached parts to move a corresponding angular distance, thereby at the same time controlling the action of the valve mechanically and automatically. The return movement of the bucket to its normal position operates to elevate the pawl-lever 7L, (see dotted lines,) so that when the next action of the bucket takes place the lever, &c., will be Lagain depressed and further rotate the shaft f, as before described.

In theimproved water-motor the buckets are so arranged that the counterpoise is quickly changed by means of water overfiowing from the main into the auxiliary chambers or extensions, thereby at the same time developing comparatively great force by the thus sudden shifting of the water or leverage. In order to reduce the shock incident to arresting the angular movements of the bucket a, as in swinging back and forth, it is preferred to employ yielding stops, as n. These may be adjustable and secured to the side frames fm or arranged in any other suitable manner.

lhile the improvement is represented as applied to or combined with certain valveoperating mechanism, it is obvious that the device may be utilized for other purposes, where intermittent power is required. The rate of speed or oscillations of the device may be controlled by regulating the amount of water flowing from the pipe p, at the same time changing the size of the several discharge-openings correspondingly.

Having thus fully described the invention, what is clai1ned,and desired to be secured by United States Letters Patent, is-

In a water-motor, the swinging bucket inember a, comprising an upper filling-chamber D h provided with a partition i, an auxiliary chamber b2 communicating with said filling chamber, a lower filling-chamber c having a lateral extension, as c', and suitable openings through which the water is discharged from the said chambers, substantially as hereinbefore described.

In testimony that I claim the foregoing as the invention of the said ROBERT J. GILMORE I have signed my name, in the presence of two subscribing witnesses, this 30th day of October, A. D. 1896.

MARY E. GILMORE, Aclmz'm'stmzfrx of the estate of Robert J. Gz'Zf more, deceased.
